Resumo

As linhas de transmissão são essenciais para o acesso a fontes de energias limpas e acessíveis, Objetivo de Desenvolvimento Sustentável 7. Os incêndios florestais são um fator importante de degradação da qualidade da prestação do serviço público de transmissão. Este trabalho buscou construir um modelo para previsão de desligamento de uma linha de transmissão quando exposta a um incêndio florestal. Foram analisadas as características dos vãos expostos ao fogo de 12 linhas de transmissão em nível de tensão de 500 kV no Brasil, totalizando 3.998 km. Utilizou-se a técnica de regressão logística para o estudo. Foi possível chegar a um modelo com índice de acerto superior a 73% para a ocorrência de desligamentos de linhas de transmissão. Observou-se que o quantitativo de focos de incêndios, as variáveis climáticas e o tipo de bioma dos vãos são as melhores variáveis previsoras disponíveis. O aumento da temperatura tem potencial para elevar o número de desligamentos por incêndios florestais.
